Every transition metal has a different number of electrons, they go from 21-30 electrons, then 39-48 elctrons, then 71-80 electrons, and 103-112 electrons.
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.

When chemical bonds form, thermal energy supplies some of the energy needed to remove electrons from metal atoms. Also, energy is released as the electron associates with another atom. This energy contributes to the removal of electrons from metal atoms too; both processes happen simultaneously (as the electron moves away from the metal, it moves closer to the other atom. Because of this, there is a lower activation for the process than there otherwise would be). In some cases, the electron is not passed to another atom. This can occur when a high energy photon is absorbed, which ejects the electron from the metal.
Be
The element you are referring to is beryllium (Be). Beryllium is an alkaline Earth metal that has two electrons in the second energy level.
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
they all have a differnet number of electrons, but all have a charge of 1-
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
It depends on what elements are involved. Iron has two electrons in its outer shell, Lead has four. While in a metal, the outer electrons flow freely over the surface of the solid, there is no net loss or gain of electrons, the atoms do not become ionized, and are considered to still have their original number of electrons.
